Description OSIDB Bzimport 2026-01-05 10:02:17 UTC
In the Linux kernel, the following vulnerability has been resolved:

ALSA: firewire-motu: add bounds check in put_user loop for DSP events

In the DSP event handling code, a put_user() loop copies event data.
When the user buffer size is not aligned to 4 bytes, it could overwrite
beyond the buffer boundary.

Fix by adding a bounds check before put_user().
